Oil shale on postmarks and banknotes
For the 80th anniversary of the oil shale industry in Kohtla-Järve, Lembit Lõhmus designed a special stamp and envelope.
In 2016, we celebrated the 100th anniversary of the industrial extraction of oil shale in Estonia. The enterprises in the industry released a commemorative stamp and envelope for the occasion.
The oil shale industry has been recognised on the national level multiple times throughout history. In 1930, the 100-kroon banknote featuring the first oil shale factory in Estonia in Kohtla-Järve, designed by G. Reindorff, was released.
